Vehicle control device
During execution of steering reaction force control, when a lane change of a host vehicle is made, a vehicle control device sets a steering reaction force given to a steering operation in the direction of the lane change of the host vehicle to a reaction force of a smaller value than a reaction force of a standard value. Further, when a vehicle approach condition that another vehicle traveling in a lane on a side to which the lane of the host vehicle is to be changed is approaching the host vehicle from behind is met at the time when a lane change of the host vehicle is made, the vehicle control device does not set the steering reaction force given to the steering operation in the direction of the lane change of the host vehicle to a reaction force of a value smaller than the standard value.

the controller being configured such that, during execution of the steering reaction force control, when a lane change of the host vehicle is not made, the controller gives a reaction force of a standard value to the steering operation as the steering reaction force, and when a lane change of the host vehicle is made, the controller sets the steering reaction force given to the steering operation in a direction of the lane change of the host vehicle to a reaction force of a smaller value than the reaction force of the standard value, wherein
the controller is configured such that, during execution of the steering reaction force control, when a vehicle approach condition that another vehicle traveling in a lane on a side to which a lane of the host vehicle is to be changed is approaching the host vehicle from behind is met at a time when a lane change of the host vehicle is made, the controller does not set the steering reaction force given to the steering operation in the direction of the lane change of the host vehicle to a reaction force of a value smaller than the standard value, and
the controller is configured such that, during execution of the steering reaction force control, when the vehicle approach condition is met after a lane change of the host vehicle is started and the host vehicle starts to enter an adjacent lane and before entry of the host vehicle into the adjacent lane is completed, the controller sets the steering reaction force given to the steering operation in the direction of the lane change of the host vehicle to a reaction force of a value smaller than the standard value, and also sets the steering reaction force given to a steering operation in the opposite direction from the direction of the lane change of the host vehicle to a reaction force of a value smaller than the standard value.
2. The vehicle control device according to claim 1 , wherein the controller is configured such that, during execution of the steering reaction force control, when the vehicle approach condition is met at a point in time when a lane change of the host vehicle is started, or when the vehicle approach condition is met after a lane change of the host vehicle is started and before the host vehicle starts to enter an adjacent lane, the controller sets the steering reaction force given to the steering operation in the direction of the lane change of the host vehicle to a reaction force of a value larger than the standard value, and sets the steering reaction force given to the steering operation in the opposite direction from the direction of the lane change of the host vehicle to a reaction force of a value smaller than the standard value.
3. The vehicle control device according to claim 1 , wherein the controller is configured such that, during execution of the steering reaction force control, when a lane change of the host vehicle is started and entry of the host vehicle into an adjacent lane is completed, the controller sets an increase rate of the steering reaction force given to the steering operation in a direction of the lane change of the host vehicle relative to an amount of the steering operation to be higher than the increase rate before entry of the host vehicle into the adjacent lane is completed.
4. The vehicle control device according to claim 1 , wherein the controller is configured such that, during execution of the steering reaction force control, when, after a lane change of the host vehicle is started, a steering operation in the opposite direction from a direction of the lane change of the host vehicle is performed at some point during the lane change of the host vehicle and entry of the host vehicle into an original lane is completed, the controller sets an increase rate of the steering reaction force given to the steering operation in the opposite direction from the direction of the lane change of the host vehicle relative to an amount of the steering operation to be higher than the increase rate before entry of the host vehicle into the original lane is completed.
5. The vehicle control device according to claim 1 , wherein the controller is configured such that, during execution of the steering reaction force control, when the vehicle approach condition that has been once met ceases to be met at a time when a lane change of the host vehicle is made, the controller sets the steering reaction force given to the steering operation in a direction of the lane change of the host vehicle to a reaction force of a smaller value than the reaction force of the standard value.
6. A vehicle control device comprising a reaction force generator that gives a steering reaction force to a steering operation performed by a driver on a host vehicle, and a controller that executes steering reaction force control of controlling a value of the steering reaction force,
the controller being configured such that, during execution of the steering reaction force control, when a lane change of the host vehicle is not made, the controller gives a reaction force of a standard value to the steering operation as the steering reaction force, and when a lane change of the host vehicle is made, the controller sets the steering reaction force given to the steering operation in a direction of the lane change of the host vehicle to a reaction force of a smaller value than the reaction force of the standard value, wherein
the controller is configured such that, during execution of the steering reaction force control, when a vehicle approach condition that another vehicle traveling in a lane on a side to which a lane of the host vehicle is to be changed is approaching the host vehicle from behind is met at a time when a lane change of the host vehicle is made, the controller does not set the steering reaction force given to the steering operation in the direction of the lane change of the host vehicle to a reaction force of a value smaller than the standard value, and
the controller is configured such that, during execution of the steering reaction force control, when, after a lane change of the host vehicle is started, a steering operation in the opposite direction from a direction of the lane change of the host vehicle is performed at some point during the lane change of the host vehicle and entry of the host vehicle into an original lane is completed, the controller sets an increase rate of the steering reaction force given to the steering operation in the opposite direction from the direction of the lane change of the host vehicle relative to an amount of the steering operation to be higher than the increase rate before entry of the host vehicle into the original lane is completed.
